SmartSound
Peer-reviewed foundations

Every Hz, every soundscape, every protocol — grounded in published research.

SmartSound is not a "vibes" app. Each frequency band, each noise color, each ramp duration traces back to peer-reviewed neuroscience. Below are the ten papers our adaptive engine is built on. Read them, verify them, hold us accountable.
